2 Page 1 of 5 Acoustical Performance Test Report KOLAY FLOORING INTERNATIONAL, LLC Currier Road Suite 300 Industry, California Report H Test Date 05/31/17 Report Date 06/02/17 Project Scope Architectural Testing, Inc., an Intertek company (Intertek-ATI), was contracted to conduct airborne sound transmission loss and impact sound transmission tests. The complete test data is included as attachments to this report. The full test specimen was assembled on the day of testing by Intertek- ATI. All materials provided by the client were installed on an existing Intertek-ATI assembly (Open Web Truss mm) utilizing Intertek-ATI-supplied materials. Test Methods The acoustical tests were conducted in accordance with the following standards. The equipment listed in the attachments meets the requirements of the following standards. ASTM E (2016), Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions ASTM E , Classification for Rating Sound Insulation ASTM E (2016)e1, Standard Test Method for Laboratory Measurement of Impact Sound Transmission Through Floor-Ceiling Assemblies Using the Tapping Machine ASTM E (2012), Classification for Determination of Impact Insulation Class (IIC) ASTM E (2012) Standard Test Method for Determination of Decay Rates for Use in Sound Insulation Test Methods Test Procedure All testing was conducted in the VT test chambers at Intertek-ATI located in Lake Forest, California. The microphones were calibrated before conducting the tests. The airborne transmission loss test was conducted in accordance with the ASTM E 90 test method using the single direction method. Two background noise sound pressure level and five sound absorption measurements were conducted at each of five microphone positions. Four sound pressure level measurements were made simultaneously in both rooms, at each of five microphone positions Commercenter Drive Lake Forest, CA p f

3 Page 2 of 5 Test Procedure (Continued) The impact sound transmission test was conducted in accordance with the ASTM E 492 test method. Two background noise sound pressure level, two sound pressure level measurements with the tapping machine operating at each position specified by ASTM E 492, and five sound absorption measurements were conducted at each of five microphone positions. The air temperature and relative humidity conditions were monitored and recorded during all measurements.
